Mysql batch imports text data into the database C language (c api), mysqlapi

In fact, the principle is very simple. I think everyone should have read the article I wrote (a code learns to operate databases in C) on linux, the basic student information management system (add, delete, query, and modify to display) is implemented by operating the database in C language. Where is the insert function ), then, use the sprintf function to format and write it into the execution statement."Add"Same.

The Code is as follows:

# Include <stdio. h> # include <stdlib. h> # include <string. h> # include <mysql. h> MYSQL;/****** import data to the database in batches using the insert into command ******/void insert (char * a, char * B, char * c) {int t, r; char query [400]; memset (query, 0,400); sprintf (query, "insert into EnglishWord4 (Words, Translate, Num) values ('% s',' % s', '% s') ", a, B, c); // Insert the table printf (" executing: % s \ n ", query); t = mysql_real_query (& mysql, query, (unsigned int) strlen (query); if (t) {p Rintf ("exception occurred during insertion: % s", mysql_error (& mysql);} else {printf ("added successfully \ n") ;}} int main () {FILE * fp; char buff [300]; fp = fopen ("englishword4.txt", "r"); // open different files if (fp = NULL) {printf ("Fail to open \ n"); exit (1);} MYSQL_RES * res; MYSQL_ROW row; mysql_init (& mysql); if (! Mysql_real_connect (& mysql, "localhost", "root", NULL, "English", 0, NULL, 0) {printf ("Error connecting to database: % s ", mysql_error (& mysql);} else {printf ("Connected... \ n ") ;}char * p; char a [20]; char B [200]; char c [10]; int length = 0; while (fgets (buff, 300, fp )! = NULL) {if (buff [strlen (buff)-1] = '\ n') {buff [strlen (buff)] =' \ 0 ';} strcpy (a, strtok (buff, "#"); int I = 0; while (p = strtok (NULL ,"#"))) {if (I = 0) {// printf ("Skip \ n") ;}if (I = 1) {strcpy (B, p );} if (I = 2) {strcpy (c, p) ;}++ I ;}length = strlen (c); c [length-2] = '\ 0 '; insert (a, B, c); bzero (a, sizeof (a); bzero (B, sizeof (B); bzero (B, sizeof (c ));} mysql_close (& mysql); fclose (fp); return 0 ;}

You can try appending an operation table. This is my format.

Simple thinking

Result:

Start table search results

Create the table and display content of the imported data

Execute the insert program:
